secondary spindle to the lower end 25' is 'nemovably connected of; the main spindle 22, and

is provided at itslower end with a cutter 26'.

The secondary spindle 25 is provided with flat portions 27. to permit it to be connected to and disconnected from the main spindlel' 22 by a wrench or other suitable tool. main spindle 22'is adapted to be adjusted axially or vertically with respect to the 1 sleeve 19 to position the cutter 26 incontact with the valve seat after the bracket lhas been secured to the valve fiange andit is secured in its adjusted position by nuts 28:

The cutter 26 is rotated at low speed when reseating a valve of steel and at high speedwhen reseati'ng a valve of brass,

Theshaft 30 is secured against'endwise displacement by collars 33 secured'thereto and contacting with the ends of the bushing 12. To permit the machine to be operated a hand crank 34 is secured to thevshaft 30.

From the foregoing description,-taken in connection with the accon'ipanying drawing, it should be apparent that the machine may be readily and firmly secured to valves of different sizes, and that, it may be operated at low speed to adapt it for reseating steel valves and at high speedto adapt it for reseating brassvalves. Any sized cutter may be used in connection withthe machine. To

prevent any oscillation of the upper end of y the sleeve 19 during the usetof the machine,

' a strap 35is provided, and has an opening 36 for the reception of the upper end of the sleeve and is removably secured to the upper end ofthe arm 8 by a cap screw 37. i A WVhile ave have described what we now consider to be the best embodiment ofthe invention we desire to have it understood that the device shown is merely illustrative, and that suchchanges may be made when tion as claimed.

, lVhat is claimed is:' A'valve reseating machine comprising an desired as are within the scope of the inveninverted U-shaped attaching and supporting bracket provided in its cross member with a bearing, arms extending outwardly from the side members of the bracket and provided with longitudinally extending slots, a sleeve extending through the bearing, elements carried by the sleeve at opposite'sides of the cross member, bearings surrounding the sleeve and positioned between the elements and vcrossmember, a threaded spindle carried by the sleeve for endwise adjustment with respect thereto, means preventing any relative rotation between the sleeve and spindle, retaining elements mounted on the spindle and contacting with the ends of the sleeve, an arm secured to the bracket and extending beyond the samein parallel relation to the sleeve, a-strap secured to the arm and havingan opening for the reception of.

the sleeve, a gear keyed to the sleeve, and

provided with inner and-outer rows of teeth,

a shaft journaled insaid last arm between. said cross member and gear andextending inwardly andoutwardly beyond the rows of. teeth of the gear, a pinion provided with inner and outer rows of teeth and adjustably mounted on the shaft for engagement with one of the rows of teeth of the gear, and

means for 'securingthe pinion in adjusted;

position on the shaft. I

In testimony whereof we afiix our signatures.
